Claims. 1

This invention relates to new and useful improvements in windowstructures and the primary object of the present invention is to providea window structure including a plurality of outwardly swingable closuremembers together with a manually actuated lever for simultaneouslyraising all of said closure members.

' Another very important object of the present invention is to provide awindow structure including a group of unitarily swinging closure membersand a means for retaining or locking the closure members in a selectedraised position and against accidental closing.

A further object of the present invention is toprovide a windowstructure composed of a plurality of outwardly swinging closure memberswith the adjacent horizontal edges of adjacent members being rabbeted topermit interlocking of adjacent members when they are in their closedposition.

A still further aim of the present invention is to provide a windowstructure that is quickly and readily assembled or disassembled in aconvenient manner, and which is neat and attractive in appearance,strong and durable in use, simple and practical in operation,inexpensive to manufacture, and otherwise Well adapted for the purposesfor which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

- a. Figure 1' is a front view of the present invention; partly inelevation and partly in section;

Figure 2 is a side elevational view of Figure 1 and with dotted linesshowing the closure members raised to their maximum position and theactuating lever lowered to its maximum position;

Figure 3 is a longitudinal vertical sectional view taken substantiallyon the plane of section frame composed of a pair of vertical side railsI2 and I4 having upper and lower grooves I6 and I8 in their inner facesand adjacent their ends that receive the ends of upper and lower crossrails 20 and 22.

A plurality of closure members or window sashes 24 are associated withthe frame and are mounted upon the frame for-vertical swinging movementin a manner now to be described. The

ends of the closure members 24 ,areprovided with recesses 26 thatreceive'anchor plates 28. The plates 28 are held in the recesses 26 byfasteners 30 that extend through the plates and into the ends of theclosure members. Y.

The plates 28 are located relatively close to th upper edgesof theclosure nriemliners and the plates 28 hold thev reduced threaded innerends of horizontally projecting trunnionsor pivots 32 having splinedouter ends 34. 7 1, The side rails I2 and I4 are provided withverticallyspaced horizontal openings 36 in each of which there is fitted a hearingsleeve 38. The sleeves 38 rotatably support the trunnions 32 and theends 34 of the trunnions project-outwardly from the side rails I2 and I4to ,e nter splined openings 40 in the enlarged ends 42' of connectingarms 44. Set screws 46 threaded in'the ends 42 bear against the ends 34of thetrunnions to hold the arms 44 on the trunnions. I ,l I Theadjacent horizontal edges of adjacent closure members are rabbeted as atR, to permit interlocking of adjacent closure members when the closuremembers are moved to their closed position as shown in Figure v3. Y

The lower most of the openings 36 in the side rails are located belowandparallel to the crossrail 22 and the bearing sleeves 38 thereinrotatable support a strengthening rod or rock shaft 48 whose splinedends project from the rails I2 and I4 to support lower arms 45 similarto the arms 44. 1 j

A connecting bar 50 is pivoted, as at 5|, to each of the arms 44 thataremounted on the trunnions projecting through the rail I2 and to thearm 45 on one end of the shaft 48. Another connecing bar 52 is pivoted,as at 54, to each of the arms 44 that are mounted on the trunnionsprojecting through the rail I4 and to the arm 45 on the other end of theshaft 48. 7

An actuating lever 54 is pivoted, as at 56, to the rail I2 at aconveniently accessible position and is attached to the bar' 50 by ahorizontal pivot 58 so that a lowering of the-lever 54 will effect araising of the bar 50, directly, and will cause the closure members andthe bar 52 toalso be raised. The opening in the lever 54 through whichthe pivot 58 extends; is sufliciently large as to permit the lever to bemanually urged horizontally or laterally of the-rail I2 and the bar 50for a purpose later to be described.

The free upwardly curved end portion 60 of the lever 54 supports afinger grip or knob 62 which permits a convenient handling of the leverduring raising or lowering of the closure members.

Means is provided for locking the closure memlever 54 and a verticalslot 69 is provided in the.

trim T to prevent the lever from springing out of place.

The upper rail 20 supports a horizontalsealing strip that will contactthe upper rabb'eted edge ports a lower'sealing strip 12 that willcontact the lower rabbeted edge of the lowermost closure member when thelowermost closure member is in its closed position/as shown in Figure 3,toproperly seal 'theclosure's to the frame and to each. Obviouslyadditional vertical resilient sealing strips may be applied to =theinner faces of the rails l2 and to :close the slight space between theends of the closure members and the rails 12 and I4. M

The rails l2, i4, 26 and 22 are provided with ribs 74 to which there issecured a screened frame member 76. The frame member 16 is readilyremoved and may be replaced by a storm sash during cool weather. I

The recesses 26 extend to the upper edges of the sash so that when thesash is open; the fasteners 30 maybe'removed and the sash slipped fromthe plates'28 without having to remove any other parts.

The's'a'sh may be easily cleaned from the inside of the building bysimply removing the screen. Also, the window structure is ofan awningtype that will provide full ventilation as well as refleeting the sunout or the room. Furthermore, the sash may remain open during aWindstorm.

Additionally, there are no rods, bars or anything to obstruct the viewthrough the sash nor is there anything to collect dust or mar its beautyexcept one small knob used for opening and closing the sash. 1

Having described the invention, what is claimed as new is:

4. A window structure comprising an open frame including a pair ofvertical side rails, a plurality of closure members within said frameand including ends paralleling said rails, anchor plates secured to theends of said closure members, horizontally projecting trunnionssecuredto said plates and extending through. said rails, each of saidtrunnions having an outer splined end projecting from said rails,connecting arms having splined openings receiving the splined ends'ofsaid trunnions, a first connecting bar pivoted to the arms on thetrunnions extendingthroug'h one side rail, a second connecting barpivoted to the arms on the trunnions extending through the other siderail, a rock shaft on the frame paralleling the trunnions and pivoted toboth bars, an actuating lever pivoted on said frame and also pivoteddirectly to said first bar for raising said closure members, and avertical retainer on said frame adjacent said first ,bar and including aflange having a plurality of vertically spaced notches for selectivelyreceiving said lever to retain the closure:members in a selected raisedposition. i
